Railway roadbed



travel therebetween. The slab I5 itself is also locked from-lateral deviation by seating in the depressed portion of the roadbed afforded by the sleeves I0c. Further, the sections of the road-` bedare joined in a longitudinal series by the periodical cross-members and are prevented from lateral movement by the terminal projections or stops of such cross-members. Altogether, the novel roadbed is safe in preventing the wheels of the rollingequipment from falling off the rails in case of a broken aXle or other mishap; and the roadbed is at all times serviceable for a highway for all vehicular trafdc, so that it may be so used in case overflow traffic space is required, as in the event of special or wartime transportation.

While I have described the invention along specific lines, various minor changes and rene` ments may be made therein from time to time without departing from its principle, and I consider all such changes and refinements as coming within the scope and spirit of the appended claims.

I claim:-

l. A roadbed for railway tracks comprising a longitudinal series of concrete members serving as ties,- and means to unite the members at the joints to form a continuous support for the tracks comprising abutting portions of said members transversely recessed from underneath to form a bottom channel along the line of the joint, and a cross member seating in said channel.

2. The structure of claim 1, and upward projections from the ends of the cross-memberalongside the joined members.

3. A roadbed for 'railway tracks comprising a concrete base longitudinally recessed in its upper surface, and supports adjoining the sides of 'the recess to seat the rails so that the outer sides of the heads thereof abut the sidesof the recess said supports being raised from the floor of said recess, and a ller slab seating on said oor of said recess between said supports, lthe outer ends of said slab being in substantially abutting relation with the inner edges of said supports.

4'. A roadbed for railway tracks comprising a concrete base longitudinally recessed in its upper surface, suppor's adjoining the sides of the recess to seat the rails so that the outer sides of the heads thereof abut the sides of the recess, and a ller slab in said recess and lling the space between the inner base flanges of the rails.

5. The struc.ure of claim 3, said supports being shelves inwardly directed from the sides of the recess and terminating evenly with the edges of the inner base flanges of the rails.

6. A roadbed for railway tracks comprising a concrete base longitudinally recessed in its upper surface, supports adjoining the sides of the recess to seat the rails so that the outer sides of the heads thereof abut the sides of therecess, said supports being shelves steppedup from the bottom of the recess, securing means for each rail directed into said bottom along the inner sides of the rails to clamp the inner base flanges thereof to said shelves, and a ller slab seating on said bottom between the shelves, said slab being recessed from underneath to clear said securing means.

7. A roadbed for railway tracks comprising a concrete base longitudinally recessed in its upper surface, supports adjoining the sides of the recess to seat the rails so that the outer sides of the heads thereof abut the sides of the recess, said supports being shelves stepped up from the bottom of the recess, securing means for each rail directed into-said bottom along the inner sides of the rails'to clamp the inner base flanges thereof to said shelves, and a longitudinal series of ller slabs `along the inner sides of the rails and seating on said bottom, said securing means occurring adjacent to the meeting lines of the slabs, and the latter being recessed from underneath in the zones of the-securing means to accommodate the same.

8. The structure of claim 1, said continuous support being longitudinally recessed in its upper surface, supports adjacent the sides of the recess to seat ihe rails so that the outer sides of the heads thereof abut the sides of the reces's, said supports being shelves stepped up from the bottom of the recess, securing means for each rail directed into said bottom along the inner sides of the rails to clamp the inner base flanges thereof to said shelves, and a iller slab seating on said of the rails to clamp the inner base flanges` thereof io said shelves, anda longitudinal series of ller slabs along the inner sides of the rails and seating on said bottom, said securing means occurring adjacent to the meeting lines of the slabs, and the latter being recessed from underneath in the zones of the securing means to accommodate the same.

10. A roadbed for railway tracks, comprising a concrete base longitudinally recessed in its upper surface, said recess being of a size and shape yto seat the rails so that the outer sides of the heads ihereof abut the sides of the recess, and a filler slab in said recess, the upper surface of said slab being flush with the upper surface of the rail heads, the end surfaces of said slab being in abutting relation with the inner edges of the inner base flanges of said rails to maintain said rails in position in said recess and provide a groove above the base flange between the inner side surfaces of the rail heads and webs and the end surfaces of said slab.
